Protected persons may be compelled to work only to the same extent as nationals of the Party to the conflict in whose territory they are. If protected persons are of enemy nationality, they may only be compelled to do work which is normally necessary to ensure the feeding, sheltering, clothing, transport and health of human beings and which is not directly related to the conduct of military operations. In the cases mentioned in the two preceding paragraphs, protected persons compelled to work shall have the benefit of the same working conditions and of the same safeguards as national workers, in particular as regards wages, hours of labour, clothing and equipment, previous training and compensation for occupational accidents and diseases. If the above provisions are infringed, protected persons shall be allowed to exercise their right of complaint in accordance with Article 30.
